Presently National Space Development Agency of Japan (NASDA) envisages a lunar exploration development scenario composed from three stages of: (1) unmanned exploration including observation from circumlunar orbit, mobile exploration on lunar surface, and sampling and returning of lunar materials; (2) manned exploration; and (3) lunar development and utilization. For lunar landing and mobile exploration after observation from circumlunar orbit, researches are in progress for landing technology and lunar surface roving technology. Development of lunar surface landing technology is common and essential for development of these technologies. This research is a study on the flight orbit at time of lunar surface landing. Flight orbit gained from this study is expected to be useful as reference model in specification requirements for propellant consumption, propulsion system, and navigation guidance and control system. This report includes research results on following items: (1) system summary of lunar experiment spacecraft (system summary, mission of lunar experiment spacecraft, system specification); (2) outline of landing orbit (assumptions, outline of orbit); (3) details of orbit (Homan orbit phase, minimum propellant consumption orbit phase, analysis of final landing orbit phase parameters); and (4) conclusion, summary, and remaining research themes etc.
